Description

These Oxygen Absorbing beer bottle caps have a special liner that absorbs oxygen in the bottle's head space. This helps reduce the oxidation that happens during the bottling process, keeps your home brewed beer tasting fresher, and can extend it's shelf life.

Important to note: It is recommended that you only sanitize as many caps as you'll require at the time of bottling. The oxygen-absorbing agent is activated when the cap gets wet. If wetted caps are saved for later use, they'll still function as a normal cap, but the oxygen absorbing agent may be depleted.

Matthew C on Nov 16, 2020
has anyone had issues with these considering you can't sanitize them? anything the beer touches i prefer to be sanitized.
Josh Smith on Mar 28, 2018
BEST ANSWER: It is OK to sanitize these caps but we recommend only sanitizing as many caps as you'll need on bottling day. The oxygen-absorbing agent in the cap liner is activated when wet. If unused sanitized caps are saved for later use, they will still function as a normal cap, but their ability to absorb oxygen may be depleted.

No sanitizer problem
I used the caps on a couple of cases of Bourbon Oak Stout. Dropped them in Star San, didn't have any issues with carbonation. And I'll Star San everything, my self, the cat, the dog, h**l the old lady if she gets too close to the beer. All was good.
